Product details
Overview
AP130-15RL-7 from Diodes Incorporated is a 300mA fixed-output 1.5V low-dropout linear regulator in SC59R package, featuring 400mV dropout at full load, ±2% output accuracy, and 50µA quiescent current. It integrates PMOS pass element with no base current draw, thermal shutdown, and current-limit protection-designed for battery-powered devices requiring stable low-voltage rail generation.
For engineers reviewing the AP130-15RL-7 datasheet, AP130-15RL-7 pinout, AP130-15RL-7 application, or AP130-15RL-7 equivalent, key selection criteria include dropout performance at 300mA, SC59R thermal resistance (250°C/W), 1.5V output tolerance, fast transient response, and compatibility with 1µF/10µF input/output capacitor configuration.
Technical Context
The AP130-15RL-7 uses a PMOS pass transistor with internal 1.5Ω RON, enabling ultra-low quiescent current and eliminating base drive requirements. Its error amplifier compares feedback against a 1.08V bandgap reference to regulate output voltage with <40mV load regulation across 1–300mA.
Protection circuitry includes fold-back short-circuit current limiting (150–300mA) and thermal shutdown triggered at ~125°C junction temperature. PSRR reaches 58dB at 100Hz, supporting noise-sensitive analog and RF subsystems powered from noisy sources.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.5V ±2% - ensures stable core logic or analog sensor supply within tight tolerance |
| Max Output Current | 300mA - supports microcontrollers, USB peripherals, and small displays without external boost |
| Dropout Voltage | 400mV at 300mA - enables operation down to 1.9V input, critical for single-cell Li-ion or alkaline systems |
| Quiescent Current | 50µA typical - extends battery life in always-on or sleep-mode applications |
| Line Regulation | 0.1–0.3%/V - maintains output stability despite input sag during pulsed loads |
| PSRR | 58dB at 100Hz - suppresses switching noise from upstream DC/DC converters |
| Thermal Resistance θJA | 250°C/W (SC59R) - defines maximum power dissipation (125mW at ΔT=31.25°C) on standard FR-4 PCB |
Pinout & Package
AP130-15RL-7 is packaged in SC59R-a lead-free, RoHS-compliant 3-pin SOT-23 variant with reversed pinout versus SC59. Thermal performance is optimized for low-cost PCB layouts with minimal copper area.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (GND) | Ground Reference | Return path for error amplifier, bandgap, and thermal shutdown circuits; must connect to low-impedance ground plane |
| 2 (OUT) | Regulated Output | Delivers 1.5V ±2% to load; requires ≥10µF ceramic capacitor to ground for stability |
| 3 (IN) | Input Supply | Accepts 2.7–5.5V; minimum 1µF bypass capacitor required to limit input impedance at high frequency |
Key Features
| Feature | Design Value |
|---|---|
| PMOS Pass Element | Eliminates base current draw and enables near-zero quiescent current across full load range |
| Current Limit Fold-Back | Reduces short-circuit power dissipation to <100mW, preventing thermal runaway during fault conditions |
| Thermal Shutdown Threshold | Triggers at ~125°C junction temperature and auto-recovers after cooldown, enabling robust field operation |
| Green Molding Compound | Halogen-free (no Br/Sb) construction compliant with environmental standards for consumer and industrial use |
| Fast Transient Response | Stabilizes within 10µs after 100mA load step, minimizing voltage dip in digital processor supply rails |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-1502E/TT | 250mA max output, 170µA quiescent current, SOT-23 package | Limited to lower current loads; higher IQ reduces battery runtime in ultra-low-power designs | Select when footprint compatibility with Microchip ecosystem is prioritized over current capability |
| TPS7A0515PDBVR | 200mA max output, 25µA IQ, 175mV dropout at 100mA, 5-pin SOT-23 | Lower dropout but reduced current rating; requires additional enable pin routing | Prefer for sub-200mA applications where ultra-low IQ and tighter dropout dominate design constraints |
Compared with MCP1700T-1502E/TT and TPS7A0515PDBVR, AP130-15RL-7 delivers 50% higher output current at half the quiescent current of the former and maintains full 300mA capability where the latter derates below 200mA-making it optimal for compact, battery-constrained systems needing both headroom and efficiency.

FAQ
What is the minimum input voltage required for AP130-15RL-7 to maintain regulation at 300mA?
The AP130-15RL-7 requires VIN ≥ VOUT + VDROP = 1.5V + 0.4V = 1.9V to sustain regulation at full 300mA load. Below this, output voltage collapses linearly with input; datasheet specifies 2.7V minimum operating input to guarantee all specifications across temperature and process variation.
Can AP130-15RL-7 be used with ceramic output capacitors only?
Yes-AP130-15RL-7 is stable with ≥10µF X5R/X7R ceramic capacitors on the output. Unlike older LDOs, its internal compensation does not require ESR-based damping, eliminating need for tantalum or aluminum electrolytic capacitors and reducing board area and cost.
Does AP130-15RL-7 have reverse polarity or reverse current protection?
No-the AP130-15RL-7 lacks reverse-input protection and permits reverse current flow from OUT to IN when VIN = 0V and VOUT > 0V. External Schottky diode or ideal diode controller is required in systems where backfeed must be prevented, such as multi-rail hot-swap applications.
How does thermal shutdown behave during continuous overload?
Under sustained short-circuit or overload, AP130-15RL-7 enters thermal shutdown at ~125°C junction temperature, ceasing output. It remains latched off until junction cools by ~20°C, then automatically resumes regulation-enabling self-recovering fault handling without system reset intervention.
